Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468256, here are decompositions:

13 + 31468243 = 31468256
97 + 31468159 = 31468256
109 + 31468147 = 31468256
229 + 31468027 = 31468256
307 + 31467949 = 31468256
409 + 31467847 = 31468256
823 + 31467433 = 31468256
997 + 31467259 = 31468256

Showing the first eight; more decompositions exist.
